AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1150 AM CST TUE JAN 12 2016

UPDATE...

LITTLE CHANGE TO PREVIOUS FORECAST. DID DECREASE CLOUD COVERAGE A
BIT THIS MORNING GIVEN CLEAR SKIES ACROSS THE AREA AND NO SIGNS OF
CLOUDS IN THE REGION. WITH DECREASING CAA THROUGH THE DAY AND
CLEARING SKIES...AFTERNOON TEMPS MAY NEED TO BE NUDGED A FEW
DEGREES WARMER.

AVIATION/18Z TAFS/...

VFR CONDITIONS WILL PERSIST THROUGH THE NIGHT AT ALL TAF SITES.
LAKE EFFECT CLOUDS SHOULD HANG AROUND JUST OFFSHORE THOUGH THAT
PERIOD AS WELL AND SOME OF THOSE SCATTERED 2KFT CLOUDS MAY
OCCASIONALLY STRAY INTO MKE AND ENW...BUT LOOKING AT LARGELY CLEAR
SKIES AT ALL SITES.

AS A TROF APPROACHES ON WEDNESDAY...CIGS WILL BEGIN TO FALL IN
THE MORNING AND CONFIDENCE IS BUILDING THAT LIGHT SNOW WILL
MOVE INTO THE AREA. CURRENT THINKING IS THAT SNOW WILL ARRIVE AT
MSN IN THE LATE MORNING AND MAKE IT TO THE LAKE BY MIDDAY. ANY
SNOW THAT DOES FALL WILL BE LIGHT AND ACCUMULATIONS WILL BE LESS
THAT 1/2 INCH.

PREV DISCUSSION... /ISSUED 305 AM CST TUE JAN 12 2016/

TODAY AND TONIGHT...FORECAST CONFIDENCE...HIGH

AN UPPER TROUGH ACROSS THE WESTERN GREAT LAKES AROUND SUNRISE
WILL MOVE EAST AND EXIT THE EASTERN GREAT LAKES TONIGHT...AS A
NORTHERN STREAM NORTHWEST JET AROUND 130 KNOTS MOVES ACROSS SOUTHERN
WISCONSIN.  THE LEFT ENTRANCE REGION OF THE JET MAX IS ACROSS
EASTERN IOWA AND NORTHERN ILLINOIS TOWARDS SUNRISE WEDNESDAY.

700 MB RH DECREASES TODAY WITH AN INCREASE JUST SOUTHWEST OF THE
FORECAST AREA LATE TONIGHT WITH A WEAK MID LEVEL SHORTWAVE.

850 MB RH ALSO DRIES BUT MOISTURE REMAINS TRAPPED BELOW A LOWERING
INVERSION.  THIS MOIST LAYER BECOMES RATHER SHALLOW THIS AFTERNOON
SO EXPECT THE STRATOCUMULUS TO SCATTER OUT OVER MOST AREAS.  LOW
LEVEL MOISTURE ALSO INCREASES LATE TONIGHT JUST TO THE WEST AND
SOUTHWEST OF THE FORECAST AREA WITH A SOMEWHAT STRONGER 950 MB
TROUGH.

850 MB COLD AIR ADVECTION WEAKENS THIS MORNING AS THE INVERSION
STRENGTHENS.  LOW LEVEL COLD AIR ADVECTION CONTINUES THROUGH THE
MORNING AND LOW TEMPERATURES TONIGHT WILL DEPEND HEAVILY ON CLOUD
COVER. THE SURFACE HIGH OVER THE PLAINS MOVES MORE SOUTHEAST.  THE
PRESSURE GRADIENT RELAXES...BUT SURFACE WINDS MAY NOT BECOME CALM.

WEDNESDAY - CONFIDENCE...MEDIUM
STRONG NORTHWEST 500 MILLIBAR FLOW WILL BRING SHORTWAVE ENERGY
THROUGH SRN WI. LEADING ZONE OF DCVA ARRIVES BY EARLY AFTERNOON
WITH WAVE PASSING QUICKLY EAST DURING THE EARLY EVENING. SOME 850
WAA NOTED AS WELL AS BRIEF LEFT FRONT QUAD HELP FROM PASSING UPPER
JET MAX. QPF NUMBERS CONTINUE TO LOOK QUITE LIGHT SO SNOW AMOUNTS
UNDER AN INCH STILL LOOK GOOD. INDICATIONS CONTINUE TO POINT
TOWARDS SOME FZDZ POTENTIAL AS THE NIGHT WEARS ON WITH LOSS OF
SATURATION WITHIN THE DENDRITIC GROWTH ZONE.

THURSDAY - CONFIDENCE...MEDIUM
BROAD MID LEVEL ANTICYCLONIC FLOW. AXIS OF VORTICITY PROGGD FROM
SRN MN INTO NRN WI. 850/925 WAA REGIME IN PLACE WITH TEMPS RISING
ABV 0C. SURFACE/850 TROUGH AXIS WILL BE ACROSS MN AND IA WITH WARM
FRONTAL BOUNDARY EXTENDING INTO CNTRL WI. LOW LEVEL BAROCLINICITY
WILL SHIFT NORTHWARD WITH TIME. LLVL RH PROGS SUGGEST SOME
SCOURING OUT OF LOW CLOUD DECK THOUGH MOS KEEP THINGS ON THE
CLOUDY SIDE. BOTH GFS AND NAM BUFKIT SOUNDINGS SHOW LOW LEVEL
INVERSION WHICH MAY END UP KEEPING TEMPS A SMIDGE COOLER THAN MOS.
TRENDED TOWARDS A BLENDED SOLUTION ON TEMPS.

FRIDAY AND FRIDAY NIGHT - CONFIDENCE...LOW
GFS/GEM BOTH SHOW FAIRLY POTENT WAVE MOVING INTO THE SOUTHERN
PLAINS AND TAKING ON A NEGATIVE TILT AS IT LIFTS NEWD INTO THE ERN
GRT LAKES. THIS LEADS TO DECENT CYCLOGENESIS WITH POTPOURRI OF
PRECIP TYPES ACROSS THE AREA. MEANWHILE THE ECMWF DEVELOPS A
SURFACE LOW FURTHER NORTH AND DRAWS MOISTURE UP BUT FURTHER EAST
OF HERE WITH LITTLE OR NO PRECIP IN SRN WI. STILL A LOT OF
UNCERTAINTY SO WILL ESSENTIALLY GO WITH SUPERBLEND POPS AND KEEP
POTENTIAL FOR A MIX OF PRECIP TYPES WITH POTENTIAL FOR SNOW ON
BACK EDGE IN COLDER AIR.

SATURDAY - CONFIDENCE...MEDIUM
CAA REGIME IN PLACE IN THE WAKE OF THE DEPARTED SYSTEM. THE ECMWF
IS QUICKER IN BRINGING THE RENEWED ARCTIC SURGE. MID LEVEL FLOW
CYCLONIC SO KEPT THE SUPERBLEND POPS FOR SHSN.

SUNDAY AND MONDAY - CONFIDENCE...MEDIUM
MAIN STORY WILL BE THE COLD AIRMASS IN PLACE WITH 925 TEMPS
PROGGD INTO THE NEGATIVE TEENS CELSIUS WITH SOME POTENTIAL FOR
LOWER 20S CELSIUS.

AVIATION/12Z TAFS/...MVFR CELLING EXPECTED THIS MORNING AS A LOW
LEVEL INVERSION STRENGTHENS AND TRAPS THE LOW LEVEL MOISTURE. THIS
MOIST LAYER BECOMES RATHER SHALLOW THIS AFTERNOON SO EXPECT THE
STRATOCUMULUS TO SCATTER OUT OVER MOST AREAS. LOW LEVEL MOISTURE
ALSO INCREASES LATE TONIGHT JUST TO THE WEST AND SOUTHWEST OF THE
FORECAST AREA WITH A SOMEWHAT STRONGER 950 MB TROUGH.

NORTHWEST WINDS WILL BE RATHER BRISK THIS MORNING. NOT EXPECTING
REDUCED VSBYS OR BLOWING SNOW...BUT DRIFTING OF THE NEW DRY SNOW
COULD BE A PROBLEM IN SPOTS ON THE RUNWAYS.

MARINE...A SMALL CRAFT ADVISORY IS IN EFFECT INTO THE EVENING DUE
TO BRISK NORTHWEST TO WEST WINDS. THE WINDS WILL DIMINISH AS HIGH
PRESSURE OVER THE NORTHERN AND CENTRAL PLAINS MOVES SOUTHEAST INTO
THE MID MISSISSIPPI VALLEY THIS EVENING.
